The aim of this thesis is to develop the necessary design knowledge and tools to implement an innovative Glass Fiber Reinforced Polymer (GFRP) rebar shape in traffic railings. The innovation lies in the use of GFRP continuous closed stirrups that have become recently available. The design method is based on AASHTO-LRFD Bridge Design Specification and the latest specifications issued by the Florida Department of Transportation (FDOT) for Reinforced Concrete Traffic Barriers. After the review of existing design procedures focusing on traffic barriers and understanding the mechanical characteristics of GFRP reinforcement, a modified design approach is proposed for reducing reinforcement ratios and complexity in construction. The effort included two different type of traffic railings, namely: 36"--Single Slope (36--SS) and FDOT 32" F--Shape (F32). The 36--SS is to be used as a later time test specimen. The F32 is showcased in the Halls River Bridge Replacement Project. Finally, a Mathcad application tool developed for public use as part of the FDOT design examples library illustrates the application of this configuration for traffic barriers. Continuous close GFRP stirrups champion the versatility of the FRP composite technology by accommodating to most requirements. The use of GFRP stirrups in traffic railings complements the application of non-corrosive reinforcement in transportation structures to address the demand for sustainable construction practices.

"The reported work enclosed the numerical modeling of GFRP reinforced concrete bridge barrier under static and impact load. The GFRP configurations were designed to fit into the existing MoDOT Type D barrier structures. The constructability of the GFRP reinforcement was also taken into consideration. Both static and dynamic loading were modeled to examine the strength of the GFRP reinforced concrete bridge barrier under vehicle impact. The results showed that the designed barrier can withhold a reaction force of 200 kips, which satisfies the AASHTO specifications. The design load is also significantly higher than the impact loads generated by vehicle collision"--Abstract.

This volume contains the papers presented at IALCCE2018, the Sixth International Symposium on Life-Cycle Civil Engineering (IALCCE2018), held in Ghent, Belgium, October 28-31, 2018. It consists of a book of extended abstracts and a USB device with full papers including the Fazlur R. Khan lecture, 8 keynote lectures, and 390 technical papers from all over the world. Contributions relate to design, inspection, assessment, maintenance or optimization in the framework of life-cycle analysis of civil engineering structures and infrastructure systems. Life-cycle aspects that are developed and discussed range from structural safety and durability to sustainability, serviceability, robustness and resilience. Applications relate to buildings, bridges and viaducts, highways and runways, tunnels and underground structures, off-shore and marine structures, dams and hydraulic structures, prefabricated design, infrastructure systems, etc. During the IALCCE2018 conference a particular focus is put on the cross-fertilization between different sub-areas of expertise and the development of an overall vision for life-cycle analysis in civil engineering. The aim of the editors is to provide a valuable source of cutting edge information for anyone interested in life-cycle analysis and assessment in civil engineering, including researchers, practising engineers, consultants, contractors, decision makers and representatives from local authorities.

Corrosion-resistant, electromagnetic transparent and lightweight fiber-reinforced polymers (FRPs) are accepted as valid alternatives to steel in concrete reinforcement. Reinforced Concrete with FRP Bars: Mechanics and Design, a technical guide based on the authors’ more than 30 years of collective experience, provides principles, algorithms, and practical examples. Well-illustrated with case studies on flexural and column-type members, the book covers internal, non-prestressed FRP reinforcement. It assumes some familiarity with reinforced concrete, and excludes prestressing and near-surface mounted reinforcement applications. The text discusses FRP materials properties, and addresses testing and quality control, durability, and serviceability. It provides a historical overview, and emphasizes the ACI technical literature along with other research worldwide. Includes an explanation of the key physical mechanical properties of FRP bars and their production methods Provides algorithms that govern design and detailing, including a new formulation for the use of FRP bars in columns Offers a justification for the development of strength reduction factors based on reliability considerations Uses a two –story building solved in Mathcad® that can become a template for real projects This book is mainly intended for practitioners and focuses on the fundamentals of performance and design of concrete members with FRP reinforcement and reinforcement detailing. Graduate students and researchers can use it as a valuable resource. Antonio Nanni is a professor at the University of Miami and the University of Naples Federico II. Antonio De Luca and Hany Zadeh are consultant design engineers.

This book gathers the best peer-reviewed papers presented at the Italian Concrete Days national conference, held in Lecco, Italy, on June 14-15, 2018. The conference topics encompass the aspects of design, execution, rehabilitation and control of concrete structures, with particular reference to theory and modeling, applications and realizations, materials and investigations, technology and construction techniques. The contributions amply demonstrate that today’s structural concrete applications concern not only new constructions, but more and more rehabilitation, conservation, strengthening and seismic upgrading of existing premises, and that requirements cover new aspects within the frame of sustainability, including environmental friendliness, durability, adaptability and reuse of works and / or materials. As such the book represents an invaluable, up-to-the-minute tool, providing an essential overview of structural concrete, as well as all new materials with cementitious matrices.
